During the last quarter of the 19th century Crookes tubes were used in dozens of historic experiments to try to find out what cathode rays were. There were two theories: British scientists Crookes and Cromwell Varley believed they were particles of 'radiant matter', that is, electrically charged atoms. German researchers E. Wiedemann, Heinrich Hertz, and Eugen Goldstein believed they w… WebAnswer: What made you think electron needed a medium to travel. How do particles travel through empty space during solar flares.
